Mills, of which the followingis a specification.A

My invention is an improvement in intermediary guides placed between heating-furnaces and rolling-mills; and it'con'sists'in certain details of construction tobe more fully set forth in the following specification.

To enable others tounderstand my inven* tion, reference is had to the accompanying drawings, in which- Figure 1 is a rear elevation of a rolling-mill with myimproved adjustable guide attached thereto and a broken View of the roll-adjusting screws. Fig. 2 is a side elevation of one of the roll-housings and a sectional view of the rolls through line a of Fig. 1; also, a broken View of the front or delivery end of a furnace. Fig. 3 is a detached upper plan Vview of the guide-frame and sectional view of two of the operating-levers; also,` a broken View of a metal strip within the guide. Fig. 4 is an upper plan view of the interior'of the guideway, with a broken View of a metal strip therein. Fig. 5 is a broken detail View of the lockinglever and trip-lever adapted to engage therewith. Fig. 6 is a detail broken side elevation of one of the side guides or jaws. Fig. 7is a brokendetail View ofthe door and upper guide for the metal strip.

The construction and operation are as follows:

1 and la are the roll-housings, and 2 2fL the rolls, of an ordinary rolling-mill. The framework of the guiding device comprises the lower part 3 and the cap 4, connected to--` gether by the screws 5. When the said cap is attached, the spaces 6 and 7 are formed, in which operate the side guides or jaws 8 and 9, having the grooves 8 and 9' to engage with the edges of the metal strip fed through the guide to the rolling-mill. lt will be understood, however, that these side guides or jaws need not crowd hard against such metal strip, but simply lie close enough thereto to keep said strip in perfect longitudinal alinement with the furnace and at right angles. with the rolls.

'or jaws.

10 is the upper guide for the metal strip,

detachably connected with the cap4 by. means llis the floor, on which theV of the web 10, metal strip rests, and it is detachably con# nected' by the web 11a. The receiving ends of the said door 11 and the upper guide 10 are flared, as shown at Fig. 7, to freely admit the stock from the furnace. These said parts 10 and 1l are sufficiently narrower than the metal stripso that the side guides or jaws will in operation not come in contact with such parts;

The side guides or jaws 8 and 9 are arranged to have a parallel movement by means of the links 12, 13, 14, and 15, Fig. 4. One

end of these links is journaled to the pins 16, .17, 18, and 19, anchoredin the lower part .of the box or frame 3, which pins extend through the cap 4. The other end of saidl links is pivotally supported on the pins 20, 21, 22, and 23, anchored in the said side guides 24 and 25 are recesses in the side and near the rear'end of these guides or jaws Afor the links 12 and 14, while the large transverse opening or slot 26, Fig. 6, extends through the forward end of said guides for -the accommodation of the toes 27 and 28 and also to receive the links 13 and 15, presently to be described. The said toes are firmly secured to the vertical pins 29 and 30, pivotally supported in said guides or jaws, and such pins extend upward through the radial slots 31 and 32 of the cap 4, as shown at Fig. 3. The outer ends of the arms 33 and 34 are firmly secu red to the upper ends of pins 29 and A30, while their inner ends are pivoted to the pin 35 of the sliding bar 36, operating in the standard 37. 38 is an adjusting-screw in the standard 39 for limiting the backward travel of said sliding bar. 40 is a forked arm 'projecting from the vcap41 of standard 37, and 42 is a bell-crank lever mounted in said forked arm. The vertical arm of this bell-crank lever extends downward through a slot (not shown) near the, rear end of said sliding bar, while the horizontal arm of said bell-crank lever carries the adjustable weight 43.l

By means of the mechanism just described the inward pressure on the toes 27 and 28 is regulated and such pressure increased or decreased by simply shifting this weight 43 on its support. When the metal strip 44 is to be IOO entered into the guideway, the side guides or jaws 8 and 9 will be moved back andout of engagement with said strip. The toes 27 and 28, however, project into the feedway or feeding-line of the metal strip and engage directly with said metal strip, so as to guide it into the bight of the rolls and at right angles thereto. After the entering end of said strip projects through said rolls the side guides are moved inward toward the strip, so as to maintain the initial alin ement already established by the toes 27 and 28, in the following manner:

is a rock-shaftjournaled in the standards 46 and 47.

48 and 49 are arms resting on the outersurface of the cap 4 and swiveled by one end to the pins 50 and 5l, depending from said rockshaft, and these arms are connected to the vertical pins 52 and 53 of the side guides or jaws 8 and 9, which pins project through the radial slots 52 and These radial slots, as well as the radial slots 3l and 32, are merely intended to afford plenty of room for the pins projecting therethrough to freely operate therein.

54 is a projection of the rock-shaft 45, to which are secured the levers 55 and 56 by means of the bolt 57. AThe lever 55 is pivotally connected to one end of the horizontal operating-rod 5S. This rod is provided with the threaded end 58, and such threaded end is supported in the tilting box 59, which box has a vertical tilting movement on the pins 60. 6l is a cross-bar secured to the rods 62, and 6l is a projection of said bar, and in such projection the said tilting box 59 is pivotally hung.

The upper end of lever 56 is pivoted to the horizontal locking-lever 63. (See also Fig. 5.) Gi is a catch on said locking-lever and is adapted to engage with the upper end of the trip -lever 64. This latter lever is mounted in a forked opening in the lower end of the projection Gla and is pivotally supported on the pin G5. The horizontal arm G4 of the trip-lever carries the adjustingscrew G6, adapted to engage with the free end of the locking-lever G3 and release said lever in the mannerpresentlyto be described. The lower end of said trip-lever is provided with the toe 67, which hangs directly in the path of the metal strip 44 as it emerges from the reduction-rolls onto the surface-guide 68. This-toe is attached to the short leg G4" of the trip-lever, which leg is supported to said lever by the frictional hinge 69. When, therefore, the metal strip is fed from the furnace 70, Fig. 2, into the guideway, it is rst brought under the influence of the toes 27 and 28, Fig. 4, which toes, as before stated, guide it into the bight of the rolls. After passing through said rolls the end of said strip strikes the toe 67 of the trip-lever and, tilting the same on its pivotal suppo1't,will thus cause the adjusting-screw 66 to engage the free end of the locking-lever and release its engagement with the trip-lever. The locking-lever being thus released will be carried back in the direction of arrow Ct' by means of a weight (not shown) attached to one end of the cord 7l, connected to the rod 58. This return movement will rotate the rock-shaft 45 in the direction of arrow b, which will, as before described, carry the guides or jaws 8 and 9 in toward the strip, and thus prevent its deviatiug from the straight line established by the toes 27 and 28. When, therefore, the said metal strip has passed through the rolls, the locking-lever is again brought into engagement with the trip-lever to admit another strip from the furnace.

The nuts 72, mounted on the threaded end of rod 58, will be set so as to strike against the end of the tilting box 59, and thus limit the backward travel of such rod, and consequently the inward travel of the guides or jaws 8 and 9. Therefore a greater or less movement of these guides or jaws is regulated by the position which said nuts occupy on rod ,58.

73 is an adjusting-screw pivotally supported on the lever 55, whose threaded portion engages with the threaded clamp 74 on the lever 56, so that when the throw of the said guides or jaws is determined the position of lever 56 can be properly adjusted with respect to the engagement of the locking-lever G8 and the trip-lever 64.

The object of the frictional joint 69 of the trip-lever is to enable the toe end 67 to be raised in case of serious buckling or accident to the passing strip. If the trip-lever were not so provided, the adjusting-screw (i6 would strike against the rod 58 and break said lever; but for perfect strips the friction al joint is sufficiently stiff to effectthe tripping action.

It is im material as to how the guide-frame is supported on or near the rolling-mill. In the drawings its rear end is shown supported on the clamp 75, mounted on the bar 7G, while its front end is supported by the brace 77, projecting from said clamp. The rollingmill housings prevent lateral displacement, while the stop 78, projecting from the cap 79 IIO of said clamp, will prevent its moving backward.

The purpose of the inclosed guideway rcpresented by the bex or frame 3 and its cap is to protect thin metal plates from contact with the air on their passage from the furnace to the rolls; but an inclosed guideway, broadly speaking, is not the essential feature of my invention. In fact, the side guides or jaws, toes to engage with the forward end of a metal strip to start it squarely within the bight of the rolls before the side guides are brought forward, and the mechanism for operating said guides and toes could just as well be used on an open guideway.

A spring could be substituted for a weight to operate the mechanism for carrying the side guides or jaws up to the meta-1 strip. In

fact, the peculiar construction of all the operating mechanism could be varied without departing from the spirit of my invention, which consists, essentially, in suitable means located near the rolls for initially centering and guiding the metal strip into the bight of the rolls and side guides or jaws to be afterward brought into engagement therewith.

While I showa furnace in connection with the guideway, it will be understood that my invention is applicable to the ordinary processes of rolling metal passed to the rolls by hand.
